Public Enemy is an American hip hop group consisting of Chuck D, Flavor Flav, DJ Lord (who replaced Terminator X in 1999), The S1W group, Music Director Khari Wynn and Professor Griff who was dismissed from the group for anti-semitic remarks in 1990 but came back later in 1998. Formed in Long Island, New York, in 1982, Public Enemy is known for their politically charged lyrics and criticism of the American media, with an active interest in the frustrations and concerns of the African American community. Their first four albums during the late 1980s and early 1990s were all certified either gold or platinum and were, according to music critic Robert Hilburn, "the most acclaimed body of work ever by a rap act."
